Ether is the native currency of the Ethereum network and it’s commonly abbreviated to ETH, which is its ticker symbol.
You need ETH to pay for some of your interactions with the blockchain and to pay for the items you buy.
Adding ETH through OpenSea
You can add ETH by heading to the wallet icon, located on the top-right of the OpenSea website. You'll see a blue button titled "Add Funds".
Clicking it will prompt a pop-up window with two options:
1) Deposit from an Exchange.
For most people it’s best to find the most reputable crypto exchange, like Coinbase or Binance, which will offer a way to buy crypto with cash.
Copy your wallet address by clicking the "copy" button, and use the same address to send crypto from your exchange. You can also consult the FAQ for each exchange below.
An example of the "Deposit ETH" window. Please do not send ETH to the address above.
2) Buy with card
Depending on your locality, you may be able to buy directly with a credit card.
Buying with a credit card may incur additional fees, depending on which third-party provider you use. You may also not receive the entire crypto amount immediately.
Adding ETH through your wallet
Depending on your wallet provider, ETH may also be provided directly in your wallet.
Please see instructions below on how to purchase ETH via MetaMask.
Keep in mind, all transactions completed on the Ethereum blockchain will require gas fees. You will need enough ETH to complete your transaction on OpenSea, along with the gas fees associated with the transaction.
